The purpose of this research was to investigate the reliability of the scores produced and validity of the inferences drawn from the American Association for the Advancement of Science (AAAS, 2018) force and motion sub-topic assessment for middle school students. The assessment of student outcomes in STEM is an international focus in K-12 education. Project 2061, initiated by the AAAS, focuses on addressing challenges related to standards and assessments. This study informs this effort through testing a 14-item multiple-choice test constructed of questions from the AAAS item bank. Two samples of eighth-grade students participated (N = 1777). Rasch analysis applying the dichotomous model (Rasch, 1960) indicated sufficient item separation and reliability. Thirteen items fit the Rasch model and one item was removed for misfit. Further support for construct validity was observed with 78 percent of item ordering aligned with that predicted by physics educators and stability of measures for 11 items across the two samples. One item exhibited significant differential item functioning by gender and minority status in science. After inspection by physics educators, no bias in item wording or context was determined. Recommendation for additional items is made to increase item targeting and variance explained by the Rasch linear measure.

Introduction: This study examined psychometric properties of the Pandemic-Related Pregnancy Stress Scale (PREPS) using a Rasch Model (RM) in a large sample of pregnant women from Germany, Israel, Italy, Poland, Spain, Switzerland and the United States of America (USA).
Material And Methods: Rasch analyses were used to analyze a sample of 7185 pregnant women who completed the PREPS during the COVID-19 pandemic onset from April to August 2020. Psychological, sociodemographic, and obstetric factors were also collected and analyzed.
Conceptual and empirical item hierarchies of person-centred outpatient care.
Heliyon
January 2025
The PRO-CARE Group, Faculty of Health Sciences, Kristianstad University, Kristianstad, Sweden.
Introduction: The Person-Centred Care instrument for outpatient care (PCCoc) is a 36-item patient-reported experience measure with 4 ordered response categories, that aims to capture the degree of perceived person-centred care (PCC) from a patient perspective among persons with long-term conditions. The PCCoc is based on a framework that conceptualises outpatient PCC from lower to higher levels of perceived PCC, from personalisation via shared decision-making to empowerment, where 35 of the PCCoc items are a part of the framework's hierarchy.
Aim: To investigate to what extent empirical item responses are consistent with the hierarchical PCCoc conceptual framework among persons with long-term conditions in outpatient care.
Validation of the Arabic Version of Asthma Numeracy Questionnaire (ANQ) Among Parents of Asthmatic Children: Factor and Rasch Analyses Study.

Department of Pharmacy, Faculty of Pharmacy, Al-Zaytoonah University of Jordan, Amman, 11733, Jordan.
Background: The increasing global prevalence of asthma necessitates effective disease management, with patients and their families playing a central role. Enhancing health literacy (HL) among caregivers is critical to improving asthma outcomes.
Purpose: This study aimed to validate the Arabic version of the Asthma Numeracy Questionnaire (Ar-ANQ) to address the gap in HL assessment tools for Arabic-speaking populations.

Purpose: To develop a Chinese version of the 8-item Contact Lens Dry Eye Questionnaire (CLDEQ-8) with cross-cultural adaption and clinical validation among soft contact lens wearers (SCL) in China.
Methods: The translation and adaptation of the Chinese CLDEQ-8 (C-CLDEQ-8) followed a rigorous methodological process based on cross-cultural research guidelines consisting of three main phases: 1) forward and backward translation of original CLDEQ-8 into Chinese, 2) cross-cultural adaptation performed by medical advising committee, and 3) clinical validation and repeatability test of the translated questionnaire on Chinese SCL wearers. Rasch analysis was also performed to investigate the psychometric properties of C-CLDEQ-8.
Measuring a family sense of coherence: a rasch-based study extending dyadic data analyses.
BMC Palliat Care
January 2025
RISE Research Institutes of Sweden, Division Safety and Transport, Measurement Science and Technology, Göteborg, Sweden.
Background: Family sense of coherence (FSOC) seems to reduce distress in the family and promote the well-being of the family. Therefore, getting accurate measurements for families with long-term illnesses is of particular interest. This study explores dyadic data analysis from the dyadic- and single-informant perspectives, and the measurement properties of the FSOC-S12 according to the Rasch model.
